clear colorless to yellow liquid | [Uses]
Cycloheptanone is used as a precursor for the synthesis of pharmaceuticals. A spasmolytic agent and vasodilator is produced from this chemical. They are also used in certain stereospecific enzymatic reactions. | [Synthesis Reference(s)]

Journal of the American Chemical Society, 98, p. 6717, 1976 DOI: 10.1021/ja00437a059 | [Synthesis]
Cycloheptanone is produced
by cyclization and decarboxylation of suberic
acid (1,8-octanedioic acid) or suberic acid esters
in the gas phase at 400 – 450℃ over alumina
doped with zinc oxide or cerium oxide. | [Purification Methods]
Shake suberone with aqueous KMnO4 to remove material absorbing around 230-240nm, then dry it with Linde type 13X molecular sieves and fractionally distil it through a glass helix packed column.
